It's been a decade since Mean Girls came out, but we still can't stop quoting it.

Ten years ago Gretchen Wieners had a dream and that dream was to make ‘fetch’ happen. Now a decade on from Mean Girls we can safely say, yes, Gretchen ‘fetch’ did happen. The movie which gave us Lindsay Lohan at her best and Amanda Seyfried in her film debut has offered us many memorable quotes which have become part of our lexicon. Some you can easily drop into conversation, for others it takes a bit more effort. So in celebration of Mean Girl’s 10th anniversary here’s the 10 Mean Girls quotes we’ve labeled the most ‘fetch’.

Lindsay Lohan, she'll always be Cady to us

1. “Fetch” - Gretchen WienersFetch was an adjective Gretchen Wieners was trying to make happen. Regina George wasn't a fan telling her to “stop trying to make fetch happen”, but we say no Regina ‘fetch’ has happened, at least for us.

Who could have predicted the phenomenon Tina Fey's high school comedy would prove to be?

It's ten years since hit high school comedy Mean Girls was released. Yes, yes: we know it makes you feel old and all that jazz but what's more impressive than the simple passing of 3652.4 days is how a light-hearted look at the politics of high school life has become a phenomenon as popular and relevant now as it always was and will be forever.

'Mean Girls' Turns 10: Celebrating The Most Quotable Movie Ever Made.

To recap, Lindsay Lohan plays Cady Heron, a so-called "home-schooled jungle freak" who has spent her life sheltered from the regiment of mainstream school and its minefield of social rules. Cady is dropped in at the deep end when she catches the eye of the "plastics," a trio of vain and catty girls lead by Regina George (Rachel McAdams), the iron-fisted ruler of the school's in crowd.

'Mean Girls' actor Daniel Franzese has come out in a touching and honest open letter.

So, it turns out that Mean Girls actor Daniel Franzese isn’t “too gay to function”, and FYI, he hates that saying too. The actor has written an eloquent open letter in which he publicly comes out of the closet. The letter comes a week prior to the 10th anniversary of the movie, in which he played Damian (cripes, has it really been 10 years?).

Franzese has written an open letter discussing his sexuality

The touching letter was published on Indiewire and was addressed from Franzese to his character Damian. The letter begins, “Dear Damian, It’s been a long time since our last encounter. Ten years to be exact. I was twenty-six; you were sixteen. You were proud of who you were; I was an insecure actor. You became an iconic character that people looked up to; I wished I’d had you as a role model when I was younger. It might have been easier to be gay growing up.”

Lindsay Lohan as Regina, Ms Norbury gets busted and James Franco? How Mean Girls could have been different blows our mind.

Amazingly, its been a decade since the release of Mean Girls, the movie that has become a touch stone of pop culture for millennial teens. Written by Tina Fey and starring Lindsay Lohan, Mean Girls was a pretty much perfect high school comedy that still holds up 10 years later. But now we’re learning that it all could have been a lot different, as director Mike Waters and star Daniel Franzese have both given interviews detailing the changes Mean Girls went through before making it to the big screen.

Daniel Franzese has dished some secrets on how Mean Girls could have been very different

Perhaps the most major revelation we've read is just how different the Mean Girls cast line up could have looked. Firstly Lindsay Lohan did not want to play the lead role of Cady, instead she had her eyes on what she thought was a juicier part, that of Regina George. Lindsay was in line to play Regina, but the studio just couldn’t find a convincing Cady and even Rachel McAdams auditioned for the part. Lohan was eventually told she would have to take the lead and McAdams, who had been told she was too old to play Cady was then cast as Regina George. Once everybody was in their correct roles it was clear the right decision had been made as McAdams seemed to make the young Lohan pretty nervous, thus giving the characters the correct on screen dynamic.

Larry Clark -- who wrote and directed his first film, Kids, at the tender age of 52 and in the process, broke the mold about what we should expect from a movie about teenagers -- returns to familiar ground in Bully, a striking and harrowing follow-up.

A slam-dunk natural subject for Clark, Bully follows the based-on-reality story of Marty Puccio (Brad Renfro), who along with his girlfriend Lisa (Rachel Miner) decides to brutally slay his "best friend" Bobby (Nick Stahl) as payback for a lifetime of abuse. Set in the ultra-trashy nether regions of southern Florida -- and I mean seriously, beyond-WWF trashy -- there's little to do but drive your car, play video games, have sex, and beat the crap out of your friends.

When I was in high school, I didn't have many friends. Instead, I analyzed the cliques from a distance. I even created a little chart showing where everyone sat in the cafeteria. Seeing a similar map surface about 20 minutes into Mean Girls, I can see the filmmakers and I are starting out on the same page.

Lindsay Lohan stars as new-kid-in-town Cady Heron, fresh from the plains of Africa where her parents have been studying wildlife. When her mother gets a position at Northwestern, it's back to the States where she must attend classes like everyone else. Customary first-day humiliation ensues.

Steven Spielberg's huge-budget update of "The Warof the Worlds," H.G. Wells' seminal alien-invasion novel from 1898,is a problematic blockbuster with one essential saving grace: It's profoundlyfrightening in a way that few directors have the talent to capture.

I'm not talking about masked-psycho-with-a-chainsaw scary.That's kids' stuff. This is a slow, relentless, meticulous fear. It's thefear of uncertainty, the fear of grand-scale devastation that humanityis powerless to stop. It's a fear that fills the air like a storm and creepsup your spine in a way that's hard to shake. It is a fear not unlike whatevery American felt on September 11, 2001 -- but divorced from fact andrealigned as entertainment through the subconsciously reassuring comfortof a movie theater seat and a tub of popcorn.

It's visceral, it's psychological, and it comes more fromthe terrified performances of Tom Cruise and the remarkable Dakota Fanning(the angelic 10-year-old from "Hide& Seek" and "Manon Fire") -- as a dock-worker deadbeatdad and his daughter on the run from 100-foot alien killing machines --than from the film's hyper-realistic special effects and monsters (whicharen't that different from the ones in the shamelessly corny "Warof the Worlds" rip-off "Independence Day").

The film is worth seeing just to experience this fear,which is a testament to the power of cinema.

But as infamous as "Kids" was for its grossly candid depiction of drug use and careless, even vengeful sex, it was largely fictional. "Bully" isn't quite as coarse, but may be more chilling as it is based on true events: The circumstances surrounding the very premeditated but very sloppy slaying of a malevolent south Florida delinquent who physically intimidated and verbally abused his friends until, well, they killed him.

Fascinating in a "Cops"-meets-Psychology Today, can't-help-but-look kind of way, every character in this film is a vile imbecile -- the kind of nitwits who genuinely look to angry white rapper Eminem as a role model.
